Wire-actuated encoder SGH25

Position sensor for hydraulic cylinders with measuring lengths up to 2500 mm

open expert video
Absolute wire-actuated sensor for position measurement and speed measurement in hydraulic cylinders, telescopic cylinders, and piston accumulators. Durable, reliable, and easy to integrate, based on over 30 years of experience in wire-actuated sensor technology.

Profile SGH25:

  • Measuring range 0 … 2500 mm (98.42 inches)
  • Absolute measuring system
  • Pressure-resistant up to 350 bar, pressure peaks up to 450 bar
  • High degree of flexibility, adjustable to all measuring lengths thanks to teach-in 
  • Redundant interfaces (CAT3) available
  • Safety version usable up to Performace Level d
  • Analog, CANopen, SAE J1939, CANopen Safety interfaces
